HENRY C. RICE, OF EASTHAMPTON, MASS., ASSIGNOR OF ONE-HALF OF HIS RIGHT TO M. H. JAMIESON, OF MIDDLE'IOWN, CONN.

PENCIL-SHARPENER.

SPECIFICATION formingpart of Letters Patent No. 230,338, dated. July 20, 1880.

Application filed May 24, 1880.

To all whom t may concern:

Be it know that I, HENRY C. RICE, of Easty hampton, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Pencil-Sharpeners; and I do hereby declare the following to be a full, clear, and exact description ofthe invent-ion, such as will enable others skilled in the art to which it pertains to make and 1o use it, reference being had to the accompanying drawings, which form part of this specification.

My inven tion relates to an improvement in pencil-Sharpeners5 and it consists in the combination of a shaft having a sharpener attached to itsinner end so as to revolve with it, a rotary file which is carried around by the shaft, and which is caused to revolveindependentl y of the shaft by means of a suitable gear or dezo vice of its own, and a sliding carriage which clamps the pencil and moves it forward toward the sharpener, as will bc more fully described hereinafter. I

The object of my invention is to provide a means for cutting away the wood on the pencil, and a separate and independent device for sharpening the lead at the same time, so that the point will be perfectly finished at the Msame time that the wood is cut away without any 3o danger of being broken or having to be separately finished afterward, as is the case with many of the sharpeners now in use.

Figur-el is a side elevation of my invention, partly in section. Fig. 2 is a plan view ofthe 3,5 same. Fig. 3 isan end view of the carriage for holding the pencil.

A represents a suitable hase, upon which the standard B is mounted. In the upper part of the standard is formed a hearing, O, 4o for the shaft 1), which has the driving-wheel (Model.)

in which plate is jonrualed a short shaft, on 55 which are placed afriction-wheel, of rubber or other suitable material, for bearing against the inside of the flange H, and a rotary file, L, which has its outer edge tapered, as shown. By having this plate K made adjustable a liner 6o adjustment of the file can be given. This wheel of rubber, by bearing against the inside of the recess in the top of the standard, causes the file to revolve in the opposite direction from the shaft, and independently of the shaft, upon its own axis. This revolving iile has its smaller edge to come just lush with the opening through which the point of the pencil pro-A jects in the inner end of the sharpener, and then the remainder of its edge forms the exact 7o taper which is to be given to the point. As the point of the pencil is forced inward the knife cuts away the wood at .the same time that the revolving tile gives a most perfect taper to the eudof the lead.

In order that the pencil may always beheld not only perfectly straight, but be fed forward in a steady manner, there is astand, N, made, upon the top of which are formed the two guides O. Moving back and forth upon these 8o two guides upon this stand, and just opposite to the fastener, is a carriage, Q, for holding the pencil while it is being sharpened. This carriage is pivoted upon one ot' the guides, so that it can be turned freely over upon one side, and consists of the bottom piece, which is attached to the guide, two jaws, B, and a latch, S. In between these two pivoted jaws is a block or rubber, T, which has a suitablev recess formed in its upper part for receiving 9o the pencil. When the two jaws are pressed together, so that the latehvcan fasten them in that position, the rubber clamps the pencil, so

as to hold it very firmly and securely in position, and yet without injuring the finish ofthe pencihand so as to allow the pencil to yield slightly in any direction, so as to accommodate itself to the cutter should it not be placed exactly in line with it. By means of this rubber clamp not only is the pencil not injured roo in appearance, but the pencil is left free to move just snfiiciently to have the point pnt` upon it in the most perfect manner. Reinm`Y` ably attached to the standard is the box V, which is placed just under the cutter, so as to catch all ot' the wood and the dust from the lead, and thus prevent a dirt and litter from being made.

Having thus described my invention, I claim- 1. In a peiicil-sharpener, the combination ot'v a shaft havingl a pencilsharl'iener secured 1o its end and atile that is carried around by the shal't so as to sharpen the point ofthe pencil, substantiall5T as shown.

2. In a pencil-sharliener, the combination of a shaft having' a pencil-sharpener secu red toits end with a revolving1 tile that is carried around the point ot' the pencil, and provided with a means, substantially as described, for causing' it torevolve in an opposite direction to the shaft, substantially asdescribed.

3. In a pencil-sl|arpener, the con'ibination ot' a shaft. having' a pencil-sharpener secured 1o its end, the arm l, a wheel to bear against the inside ot the iiange H, and a revolving' lile, L, the parts being.;I arranged to operate substantially as set forth.

4. In a pencil-Sharpener, the combination of a revolving shaft` having a pencil-Sharpener secured thereto, and ahorizontally-moving` car riage composed ofthe two hinged jaws R, rccessed block ot' rubber T, and a holdin ,fg-latch, S, substantially as specified.

5. The combination, in a pencil-Sharpener, of a revolving' Sharpener, al1 oppositely-revolvin g file, a carriage for holdin g' and feeding,` forward the pencil, and a box to catch the chips, substantially as shown and described.

6. The combination, in a pencil-Sharpener, ot' a revolving shaft and a suitable bearing therefor, a pencil-Sharpener, F, thatis secured to one end of the shaft, and. provided With a cutting-bl-.ide for paring away the wood of the pencil only. and a iiy-wheel or crank that is secured to the other end ot' the shaft, substantially as set forth.

In testimony that l claim the foregoing l have hereunto setI my hand this 11th da)T of May, 1880.

HENRY C. RICE.
